' CHARLES H. PELTON, OF SPRINGFIELD, OHIO, ASSIGNOR TO THE THOMASMANUFACTURING COMPANY, OF SPRINGFIELD, OHIO, A CORPORATION OF OHIO.

PRESS-DRILL.

SPECIFICATION forming part of Letters Patent No. 778,999, dated January3, 1905.

Application filed February 23, 1904. Serial No. 194,690.

To all whom, it may concern.-

Be it known that I, OHARLEs H. PELTON, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Press-Drills, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to press-drills, and has for its objectto providea construction whereby the press-wheels shall be adapted to conform intheir travel to the inequalities of the soil, while at the sametime theaxles and supporting frames are freed from undue strain.

To these ends my invention consists in certain novel features which Iwill now proceed to describe and will then particularly point out in theclaims.

In the accompanying drawings, Figure 1 is a perspective view of apress-drill embodying my invention in one form. Fig. 2' is a rearelevation of the same. Fig. 3 is a plan view. Fig. 4 is a verticalsection, and Fig. 5 is a detail perspective view of one of the parts. InFigs. 2, 3, and 4 the various parts carried by the front frame areomitted. Figs. 6 and 7 are detail views of the foot-rest.

In the said drawings, 1 indicates the front frame, rigidly connected tothe tongue 2 and carrying the seeding devices, which may be of anyapproved construction. To the rear of this front frame are hinged theframes which carry the press-wheels. In the present instance I haveshown two press-wheel frames, although the number may be varied.

3 indicates a cross-bar of the front frame 1, provided with lugs orbrackets 4, to which are pivoted the forward ends of bars 5, whichconstitute the side or longitudinal members of the wheel-frames. Eachwheel-frame also comprises a transverse member or rear crosspiece 6,connecting the rear ends of the side members 5. This connection is apivotal one, the rear end of each side member 5 being provided with apivot-stud 7, which may be formed on a cap 8, secured to the rear end ofthe member 5. The member 6 is provided with an aperture at each end toreceive the pivotvided. In the" present instance I have shown I in Fig.1 a structure embodying eight presswheels, four to each frame, while inFigs. 2 and 3 I have shown a structure having ten press-wheels, five toeach frame. Each group of press-wheels is mounted on an axle 11, andsaid axle has a bearing in sleeves 12, there being two of thesesleeve-bearings for each axle, and each sleeve-bearing being pivotallyconnected to the corresponding longitudinal member 5 of thecorresponding wheel-frame. I prefer for this purpose to provide eachmember 5 with a downwardly-extending bracket 13, having at its lower endlugs 14, apertured to receive a pivot-bolt 15. The bearing-sleeve 12 isprovided with a similar lug 16, fitting between lugs 14 and having anaperture through which the pivot-bolt 15 also passes. It will beobserved that the pivotal axes of the connections between the bearingsleeves and frame are transverse to the axle and longitudinal withrespect to the machine.

The seat-bar (indicated by the referencenumeral 17) is pivotallyconnected at its front end to the front frame, has a seat 18 adjustablethereon longitudinal at its rear end, and is provided withsupporting-bars 19, connected at their upper ends to the seat-bar and attheir lower ends to the wheel-frames. This latter connection ispreferably effected by providing the rear cross-bar 6 of eachwheel-frame with a bracket 20, secured thereon and provided with alongitudinal slot 21, extending in the direction of the length of themember 6 and adapted to receive a bolt 22, which connects it to the endof the corresponding supporting-bar 19. The bolt 22 plays freely in theslot 21 and permits free relative movement of the wheel-frames, while atthe same time the weight of the operator is duly transferred to saidwheel-frames and distributed to the wheels. The supporting-bars 19 areconnected by a cross-bar 23.

In press-drills of this class as heretofore constructed it has been thepractice to mount the press-wheels in groups in independent frames topermit the groups to adapt themselves more or less to the inequalitiesof the soil, the weight of the driver being distributed to the frames bysuitable equalizing devices. So far as I am aware, however, eachwheelframe has been a substantially rigid frame, having theaxle-bearings rigidly connected therewith, so that the severalpress-wheels of each group are maintained in substantially the samehorizontal plane, the axle being horizontal and the bearing-surfaces ofthe wheels of each group being also horizontal, so that the individualgroups of wheels are not adapted to conform to the inequalities of thesoil. By reason of the construction which I have devised the axle ofeach group is free to conform to the inequalities of the soil, one endbeing capable of tilting up,while the other end tilts downward, thistilting action being permitted by reason of the pivotal connectionsbetween the longitudinal and transverse members of the wheel-frame andthe pivotal connections between the axle-bearings and the wheel-frame.The axles are thus free to adjust themselves to the surface of theground without racking or straining the wheel-frames and the weight ofthe operator is at the same time evenly distributed to the severalwheels of each group.

In Figs. 1, 6, and 7 I have shown an improved form of foot-rest, whichis adapted for ready adjustment both vertically and longitudinally. Inthis construction the seat-bar 17 is composed of two parallel barssuitably spaced apart. 24 indicates a bolt which secures thesupporting-bar of the foot-rest in place on the seat-bar, said bar beingprovided with clips 25 and 26, fitting over the upper and lower edges ofthe seat-bar, respectively, the bolt 24: passing down between the twomembers of the seat-bar. 27 indicates the foot-rest-supporting bar, theupper end of which is so bent as to fit against the under side of theunder clip 26, the bolt 24 passing through the same and securing thefoot-rest bar in position. By sliding the clips, bolt, andsupporting-bar longitudinally on the seatbar the foot-rest may. beadjusted nearer to or farther from the seat. The body portion of thesupporting-bar 27 extends diagonally downward and forward and has thefoot-plate 28 secured on its lower end, so asto be adjustablelongitudinally of the supporting-bar, thus bringing the foot-platecloser to or farther from the seat independently of the adjustment ofthe supporting-bar and raising or lowering the foot-plate to give it thedesired height. The construction which I prefer for this purpose is thatshown, in which the footplate has a seat or recess 29, in which thesupporting-bar 27 fits, the foot-plate being provided with a stud-.bolt30 and clamping-nut 31 and the supporting-bar being provided with aplurality of apertures 32, spaced along the lower part of the same atsuitable intervals at different distances from the lower end of the bar.The bolt 30 may be passed through any desired one of the apertures 32,and the parts may then be secured in position by tightening up theclamping-nut 31.

I do not wish to be understood as limiting myself strictly to theprecise details of construction hereinbefore described, and shown in theaccompanying drawings, as the same may obviously be modified withoutdeparting from the principle of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is
